We want to use SKStoreReviewController to prompt users to review our app. Does anybody know if the 3 prompts per 365 day limit is per Apple user or Apple user on a device? For example if our app is installed on 3 devices owned by the same Apple user and all of them prompt the user to rate the app, would that exhaust all 3 prompts on all devices or would each device have 2 prompts left?
